With the Oral-B Pro-Expert battery electric toothbrush your teeth and gums will feel pampered because you're removing more plaque than a regular manual toothbrush each time you brush. This toothbrush has a soft ergonomic handle and is compatible with the entire lineup of Oral-B Toothbrushes, except for Oral-B Sonic toothbrushes. The indicator bristles on this toothbrush fade as a sign to replace the toothbrush head for a better clean (about every 3 months). Included in pack: 1 Power Toothbrush, 2x AA Batteries. Always read the packaging.
